The present invention relates to web presses and has for an 'objecttoprovide a press in which a multiple-impression unit is combined with aplurality of single-impression units.

Another object of the invention is to `provide a printing press withmeans for printing a plurality of webs in single colors and another webin multiple colors and then interleaving the multi-colored web with theother webs, at will.

It will be understood that by the term singleimpression unit, I refernot only to a printing unit which makes a single impression, but also toa perfecting press unit which prints rst on one side of the web and thenon the other, making a single impression on each face of the web.Obviously, however, since the impressions are made with separate platecylinders provided with individual inking fountains any color of ink maybe used and the color of the impression on one face of the web maybedilerent from that on the other.

In a copending application, Serial No. 512,029, illedv January 29, 1931,since issued as Patent No. 1,970,929, dated August 21, 1934,`I describea combined perfecting press and multicolor printing unit in which a webafter being led through the perfecting unit is passed through themulticolor unit and lreceives a plurality of impressions in differentcolors. Thus, while one face of the web may be printed in a singlecolor, for instance, black, the other face may be printed with say livecolors. In said application, I also provide means' for reversing onepress unit with respect to the other so that the multicolor impressionsmay be made on either side of the web,

' as may be desired. Also in said application I show a plurality of suchsingle and multiplecouples leading to a common folder. In the presentinvention, however, one multiple-impression unit is combined with aplurality of ordinary perfecting press units, but means are provided tointerleave the multicolor web with the other webs in any desiredrelation. .f

It is also within the purview of my invention to slit the web bearingthe multiple-impressions into two or more ribbons and to interleavethese ribbons between the other webs at any position desired.

Other objects of my invention will appear in the following descriptionof a preferred embodiment and thereafter the novelty and scope of theinvention will be vpointed out in theA claims.

In the drawings;

Figure l is a somewhat diagrammatic s'ide elevation, showing a pluralityof ordinary press units and one multiple-impression unit, all feedlngwebs to a single folder, with means for interleaving themultiple-impression web between any of the other webs;

Fig. 2 is a plan view of the interleaving appa- 5 ratus;

Fig. 3 is a view in section takensubstantially on the line 3-3 of Fig.1;

Fig. 4 is a detailed view illustrating a reversing clutch for themultiple-impression unit; and l0 Fig. 5 is a diagrammatic view on anenlarged scale, of the inking mechanism for a plate cylinder of themultiple color unit, illustrating the reversing rolls used in suchmechanism.

The printing'press illustrated in the drawings, 15 comprisesthree-ordinary perfecting press units A, B and C, and amultiple-impression unit D mounted over the unit A. 'I'he constructionof the different units A, B and C is substantially identical and adescription of the unit A will 20 suflice for the other units'.

As clearly shown in Fig. 1, the unit-A comprises a pair of platecylinders I0 and II with their cooperating impression cylinders I2 andI3 respectively. Each plate cylinder is provided 25 with the customaryinking mechanism. Between the impression cylinders I2 and I3 is a roll,

I 4 about which a web I 5 may be led to the impression cylinders. Thedirection in which the web is led depends upon whether the rst im- 30pression is to be made by theplate cylinder I0 or by the plate cylinderH. In the ,full line position shown the web is led about the left handside of the roll Iland then passes between the plate cylinder I0 andimpression cylinder I2. 35 Fromthe latter the web passes around acompensating roll I6 and thence back around the impression cylinder I3to receive theA impression yon its opposite facel from the platecylinder Il.

When desired, the course of the web through the 40 unit `may bereversed, as indicated by dotted lines, so that the web after passingabout the right hand side of web I4 is led between cylinders II and I3to. receive its llrst impression, then about a compensating roll I1 andback 45 around impression cylinder I2 to receive its second impressionfrom the platecylinder I0.

The unit A is driven by a motor I8 preferably located above the unit,and a chain belt I9 connects the shaft of the motor to a sprocket on 50the shaft of the impression cylinder I2.

The multiple-impression unit D which ls 1ocated above the motor I8,comprises a single impression cylinder 20, about which are located fourplate cylinders 2|, zla, 2lb, and zlc, 'rae im- 55 pression cylinder 20is driven by the motor I8 through a chain belt 22 which engages asprocket wheel 23 on the shaft 24 of the impression cylinder 20.However, the sprocket wheel 23 is not ixed to the shaft, but is adaptedto be clutched thereto by a reversing clutch mechanism, so that thedirection of rotation of the cylinder 20 may be reversed at will.

As shown in Fig. 4 the sprocket wheel 23 has fixed thereto, a bevel gear25 which meshes with a bevel gear 26 mounted on a xed stud. The bevelgear 26 in turn meshes with another bevel gear 21 which also turnsfreely on the shaft 24. A clutch sleeve 28 is spiined upon the shaft 24and is formed with clutch teeth at each end adapted to engage one or theother of the cooperatively toothed inner faces of the gears 25 and. 21.In the position shown in Fig. 4, the clutch sleeve is in meshwith thegear 21 and consequently the rotation of the cylinder 26 is reversedwith respect to that of the sprocket wheel 23. A hand lever 29 isprovided by which the clutch sleeve may be slid into engagement with thegear 25 and then the drive would be direct, or, in other words, thecylinder 20 would rotate in the same direction as the sprocket wheel 23.

When the impression cylinder 20 is reversed the inking mechanism for theplate cylinders which coact with the impression cylinder must also bereversed. As showninFig. 5, the particular inking mechanism employed isof a type in which the fountain roll must always .run in the samedirection. The apparatus comprises the usual ink basin 30 in which ismounted a fountain roll 3|. A roll 32 is adapted to pick up ink from theroll 3|, and a transfer roll 33 carries the ink from the pick-up roll tothe inking drum 34. Thence the ink is distributed by rolls and 36 to theplate cylinder 2|. Because of the regulating blade 31 the rotation ofthe fountain roll 3| and of the pick-up-roll 32 must .not be reversed.Since the rotation of the plate cylinder 2| is reversed when therotation of the impression cylinder 20 is reversed, means must beprovided for reversing the inking rolls somewhere between the pick-uproll and the plate cylinder. This reversing is effected by providing anauxiliary transfer roll 38. In the position shown by full lines in Fig.5, the roll 38 is idle, but when the rotation of the cylinder 20 is incounterclockwise direction the transfer rolls are shifted from the fullline position to the dotted line position, so that the ink is nowtransferred from the pick-up roll 32 to the first transfer roll 33 andthen to the second transfer roll 38 which leads it to the inking drum34. Any suitable means may be provided for shifting the position of thetransfer rolls 33 and 38.

As shown in full lines in Fig. 1, the web I6, after passing successivelyabout the impression cylinders I2 and I3, is guided past the motor by aset of rolls 40, 4| and 42, and thence is guided by al roll 43 to thecylinder 20, about which it passes in clockwise direction. 'I'he webreceives impressions from the plate cylinders 2|, 2Ia, 2| b and 2 Ic inthe-order named and thence is guided out of the unit D by the rolls 44,45 and 46. The web thus receives a single impression on one face fromthe plate cylinder I0 and flve impressions on the other face from theplate cylinder II and the plate cylinders 2| to 2Ic inclusive.

When it is desired to make the multiple-impressions on the opposite faceof the web the latter is led about the right hand side 0f the roll I4and thence passes ilrst around impression cylinder I3 and then aroundimpression cylinder I2. From this point the web is guided by rolls 41and 48 and then passes in reverse direction about guide rolls 45, 415,impression cylinder 20, and guide rolls 43 and 42, so that the side ofthe web which received its impression from the plate cylinder I0 is alsoprinted with impressions from cylinders 2Ic,' 2| b, 2Ia and 2| in theorder named, while the other face of the web receives a singleimpression from the plate cylinder II.

The web I5 after passing counter-clockwise about the impression cylinder2|! is led from the roll 42 about a roll 49 and up to a roll 50, whenceit is led over the unit D to the slitting and interleaving apparatus. Ifdesired, the web which passes through the unit A need not pass throughthe unit D. In such case the web follows the doted line I5a in Fig. 1from roll 4| direct to roll 46. As stated above, the units B and C aresubstantially identical with the unit A but are not provided with rollsI1, 41 and 48 since it is not necessary to reverse the direction of theweb passing throughthese units.

'I'he course of the various webs from the different units through theinterleaving apparatus may now be traced. The web from unit A whichpasses through the multiple-impression unit D is indicated by thereference numeral I5, but the web from unit A which shunts the unit D isindicated by the reference numeral |5a. The webs from units B and C areindicated by the numerals 5b and 5c. The web I5 coming either from roll46 or roll 50, passes over a drag roll 53 and under a slitter roll 54.Another drag roll 55 and slitter roll 56 is provided for the web |5a(should there be such a web). Similarly, a drag roll 51 and slitter roll58 is provided for the web I5b and a drag roll 59 and slitter roll 60for the web I5c. The slitter 56 slits the web I5a into two half webs orsheets I 5a.' and I5a". The sheet I 5a passes over the customarycompensating rolls 62 and thence over a guide roll 63 to the drag roll64 of the folder. The other sheet |5a" may be led by the same rolls tothe folder or if preferred it may be passed over turning rolls 65 and 66so as to be directly under the sheet I5a. Compensating rolls 61 areprovided for the sheet |5a also, and thence it passes over a roll 68 andon to the drag roll 64. Corresponding turning and compensating mechanismis provided for the other webs I5b and I5c which are slit into half websI5b'-I5b" and I5c'-I5c", respectively, so that all of these half websmay be brought into superposed relation to the drag roll 64 of thefolder.

As shown in Fig. 2 the web I5 is slit into two sheets I 5' and I5, andmeans are provided for inserting these sheets above or below any of theother sheets. The sheet I5 is turned toward the left, as viewed in Fig.3, about a turning bar 10, and then passes downward over aroll 1Ioutside of the other webs. The sheet I5" is turned in the oppositedirection about a turning bar 12 and thence passes downward over a roll18 at the opposite side of the webs. Rolls 18, 19, 80, 8| and 82 areprovided at different levels about which the sheet I5' may be introducedabove or below any of the other webs or half webs, and turning bars 18a,19a, 80a, 8Ia and 82a are provided to turn said sheets into parallelwith the said half webs.. Similarly, rolls 84, 85, 86, 81 and 88 areprovided for leading the Sheet l5" above or below the other'half websand turning bars "a, 85a, "a, 81a and 88a are provided to turn the sheetI5" back into parallel with the other sheets.

The assembly system is thus very exible and provides a wide variety ofinterleaving combinations. One of these combinations is illustrated inFig.2, and by full lines in Figs. l and 3. I'he half web i5b" is turnedover a pair of turning bars h and 66h, so that it runs below half webl5b', and similarly the half web lic is turned under the half web I5c.One of the half webs I5 is passed about the roll Il and turning bar a sothat it is introduced between the half-webs I5b" and I5c'. Since thereare no sheets on the right hand side of the machine, as viewed in Fig.3, the half web lf must be carried over to the left hand side of themachine. Thus, as shown, the half web I5" after passing about the rolleravoids the turning bar 85a, but passes on to the turning bar 19a. Thelatter is normally set at such an angle that the half web I5", onpassing about the bar will be turned rearward, or toward the left inFigs. 1 and 2. The half web l5" must then be passed about a roll or bar89 to turn it toward the right. The sheet l5" is thus introduced betweenthe half webs I5b' and 85h".

Obviously, the angle of turning bar 19a could be reversed so as to avoidthe use of the bar 89, but it is preferable to keep the bar 13a at itsoriginal angle so that it can be used for turning a half web I5' forwardinto parallelism with the other half webs. The turning bars are mountedin the customary manner, so that they may be adjusted as desired. Thus,referring to Fig. 2, the bar 19a, which normally lies directly over thebar "a, must be shifted backward tothe position shown so as to bring thesheet I5" into alinement with the half webs on the left hand side of themachine. Just beyond the turning bars for the sheets I5' and I5" arecompensating rolls 90, but where a bar 89 is used. the compensatingrolls may be dispensed with.

When the multi-color web is to be laid over instead of between or underthe other webs it may pursue the course of the web |5a. The half webs ateither side of the machine may be turned under the half webs at theother side by shifting the turning bars. When desired the half webs maycontinue to the drag roll without turning one set under the other.Hence, two folder forms 9| and 92 are provided for the left and rightsheets respectively.
